using the drift hd. great cam, and customer support is great but i am on my third one since january. camera would power up but nothing on the lcd so i couldnt use it. sent it back under warrenty, they sent a new one, month or two later same thing. another new one, working great so far.... but i am just waiting for it to quit again. maybe they have the bugs worked out this time. great cam, easy to use and all software update are available online. drift has taken care of me so far.
2 to 3 hour battery life in -5 f weather.
